BACKGROUND Technical Field

The present disclosure relates to a transmission method and device in awireless communication system, and more particularly to a transmissionmethod and device in a wireless communication system that a large numberof antennas are deployed at a base station side.

Related Art

Massive MIMO (Multiple-Input Multiple-Output) has become a researchhotspot for next-generation mobile communications. In massive MIMO,multiple antennas can improve communication quality by forming narrowerbeams pointing in a specific direction through beamforming. Both datachannel and control channel can improve transmission quality throughmulti-antenna beamforming.

According to the discussion of 3GPP (3rd Generation Partner Project)RAN1 (Radio Access Network), the hybrid beamforming combining analogbeamforming and digital beamforming has become an important researchdirection of NR (New Radio) system. Since analog beamforming is awideband operation, control channels using different analog beamformingvectors can only be multiplexed in TDM (Time Division Multiple), thatis, it needs to transmit control channels of using different analogbeamforming vectors on different time units. If the UE (User Equipment)performs blind detection on the DCI (Downlink Control Information) ineach time unit, the number of blind detections times of the DCI by UE isincreased, and the complexity of the UE is improved.

SUMMARY

Through research, the inventors found that by establishing a one-to-onecorrespondence between the time unit and the beamforming vector, each UEonly needs to monitor the DCI on the time unit corresponding to thebeamforming vector used by itself without blind detection for all thetime units, thus reducing the UE complexity.

Embodiment 12

Embodiment 12 illustrates a schematic diagram of wireless protocolarchitecture of a user plane and a control plane according to thepresent disclosure, as shown in FIG. 12.

FIG. 12 is a schematic diagram illustrating an embodiment of a wirelessprotocol architecture for a user plane and a control plane, and FIG. 12illustrates a wireless protocol architecture for the user equipment (UE)and the base station equipment (gNB or eNB) in three layers: layer 1,layer 2 and layer 3. Layer 1 (L1 layer) is the lowest layer andimplements various physical layer (PHY) signal processing functions, andlayers above layer 1 belong to higher layers. The L1 layer will bereferred to herein as PHY 1201. Layer 2 (L2 layer) 1205 is above PHY1201 and is responsible for the link between the UE and the gNB throughPHY 1201. In the user plane, L2 layer 1205 comprises a media accesscontrol (MAC) sub-layer 1202, a radio link control (RLC) sub-layer 1203and a packet data convergence protocol (PDCP) sub-layer 1204, and thesesub-layers terminate at the gNB on the network side. Although notillustrated, the UE may have several upper layers above the L2 layer1205, including a network layer (e.g. an IP layer) terminated at theP-GW on the network side and terminated at the other end of theconnection (e.g. Application layer at the remote UE, server, etc.). ThePDCP sub-layer 1204 provides multiplexing between different wirelessbearers and logical channels. The PDCP sublayer 1204 also providesheader compression for higher-layer data packets to reduce wirelesstransmission overhead, and provides the security by encrypting datapackets, and provides handoff support for UEs between gNBs. The RLCsublayer 1203 provides reassembling and reassembly of higher-layer datapackets, retransmission of lost packets and the reordering of datapackets to compensate for the disordered reception resulted by thehybrid automatic repeat request (HARQ). The MAC sublayer 1202 providesmultiplexing between the logical and transport channels. The MACsublayer 1202 is also responsible for allocating various wirelessresources (e.g. resource blocks) in one cell between UEs. The MACsublayer 1202 is also responsible for HARQ operations. In the controlplane, the wireless protocol architecture for the UE and gNB issubstantially the same for the physical layer 1201 and the L2 layer1205, but there is no header compression function for the control plane.The control plane also includes an RRC (Wireless Resource Control)sublayer 1206 in Layer 3 (L3 layer). The RRC sublayer 1206 isresponsible for obtaining wireless resources (i.e. wireless bearers) andconfiguring the lower layer using RRC signaling between the gNB and theUE.

Embodiment 13

Embodiment 13 illustrates a schematic diagram of an NR (New Radio) nodeand a UE, as shown in FIG. 13. In FIG. 13 is a block diagram of a gNB1310 in communication with a UE 1350 in an access network.

The gNB 1310 includes a controller/processor 1375, a memory 1376, areceiving processor 1370, a transmitting processor 1316, a multi-antennareceiving processor 1372, a multi-antenna transmitting processor 1371, atransmitter/receiver 1318, and an antenna 1320.

The user equipment 1350 includes a controller/processor 1359, a memory1360, a data source 1367, a transmitting processor 1368, a receivingprocessor 1356, a multi-antenna transmitting processor 1357, amulti-antenna receiving processor 1358, a transmitter/receiver 1354, andan antenna 1352.

In DL (Downlink), at gNB 1310, a higher-layer data packet from the corenetwork is provided to controller/processor 1375. Thecontroller/processor 1375 implements functions of the L2 layer. In theDL, the controller/processor 1375 provides header compression,encryption, packet reassembling and reordering, multiplexing betweenlogical and transport channels, and radio resource allocation for the UE1350 based on various priorities. The controller/processor 1375 is alsoresponsible for HARQ operation, retransmission of a lost packet, and asignaling to the UE 1350. The transmitting processor 1316 andmulti-antenna transmitting processor 1371 implement various signalprocessing functions for the L1 layer (i.e., the physical layer). Thetransmitting processor 1316 performs encoding and interleaving tofacilitate forward error correction (FEC) at UE 1350, mapping of signalclusters based on various modulation schemes (e.g., binary phase shiftkeying (BPSK), quadrature phase shift keying (QPSK), M-phase shiftkeying (M-PSK), M quadrature amplitude modulation (M-QAM)). Themulti-antenna transmitting processor 1371 performs digital spatialprecoding of coded and modulated symbols, comprising codebook basedprecoding and non-codebook based precoding, beamforming processing, andgenerating one or more spatial streams. The transmitting processor 1316then maps each spatial stream to sub-carriers, and the spatial streamsmultiplex with reference signals (e.g., pilots) in the time and/orfrequency domain, and then uses an inverse fast Fourier transform (IFFT)to generate a physical channel carrying a time-domain multi-carriersymbol stream. The multi-antenna transmitting processor 1371 thentransmits an analog precoding/beamforming operation to the time domainmulti-carrier symbol stream. Each transmitter 1318 converts the basebandmulticarrier symbol stream provided by the multi-antenna transmittingprocessor 1371 into a radio frequency stream, which is then provided toa different antenna 1320.

In DL (Downlink), at UE 1350, each receiver 1354 receives a signalthrough its corresponding antenna 1352. Each receiver 1354 recovers theinformation modulated onto the radio frequency carrier and converts theradio frequency stream into a baseband multi-carrier symbol stream forproviding to the receiving processor 1356. The receiving processor 1356and multi-antenna receiving processor 1358 implement various signalprocessing functions at the L1 layer. The multi-antenna receivingprocessor 1358 performs a receiving analog precoding/beamformingoperation of the baseband multi-carrier symbol stream from receiver1354. The receiver processor 1356 converts the received analogprecoded/beamforming operated baseband multicarrier symbol stream fromtime domain to frequency domain using Fast Fourier transform (FFT). Inthe frequency domain, the physical layer data signal and the referencesignal are demultiplexed by the receiving processor 1356, wherein thereference signal will be used for channel estimation, and the datasignal is recovered by the multi-antenna detection in the multi-antennareceiving processor 1358 to any spatial stream for the UE 1350destinations. The symbols on each spatial stream are demodulated andrecovered in the receiving processor 1356 and generated soft decision.The receiving processor 1356 then decodes and deinterleaves the softdecision to recover the upper layer data and control signals transmittedby the gNB 1310 on the physical channel. The upper layer data andcontrol signals are then provided to the controller/processor 1359. Thecontroller/processor 1359 implements the functions of the L2 layer. Thecontroller/processor 1359 can be associated with memory 1360 that storesprogram codes and data. The memory 1360 can be referred to as a computerreadable medium. In the DL, the controller/processor 1359 providesdemultiplexing, packet reassembly, decryption, header decompression, andcontrol signal processing between the transport and logical channels torecover upper layer packets that came from the core network. The upperlayer packet is then provided to all protocol layers above the L2 layer.Various control signals can also be provided to L3 for L3 processing.The controller/processor 1359 is also responsible for error detectionusing an acknowledgement (ACK) and/or negative acknowledgement (NACK)protocol to support HARQ operations.

In UL (Uplink), at UE 1350, data source 1367 is used to providehigher-layer data packets to the controller/processor 1359. The datasource 1367 represents all protocol layers above the L2 layer. Similarto the transmitting function at gNB 1310 described in the DL, thecontroller/processor 1359 implements header compression, encryption,packet reassembling and reordering, and multiplexing between the logicaland transport channels based on the wireless resource allocation of thegNB 1310, to implement L2 layer functions for the user plane and controlplane. The controller/processor 1359 is also responsible for HARQoperations, retransmission of a lost packet, and a signaling to the gNB1310. The transmitting processor 1368 performs modulation mapping,channel coding processing, and the multi-antenna transmitting processor1357 performs digital multi-antenna spatial precoding, includingcodebook based precoding and non-codebook based precoding, andbeamforming processing, followed by transmitting processor 1368modulates the generated spatial stream into amulti-carrier/single-carrier symbol stream, which is provided todifferent antennas 1352 via transmitter 1354 after an analogpre-coding/beamforming operation in multi-antenna transmitting processor1357. Each transmitter 1354 first converts the baseband symbol streamprovided by the multi-antenna transmit processor 1357 into a stream ofradio frequency symbols and provides it to the antenna 1352.

In UL (Uplink), the function at gNB 1310 is similar to the receivingfunction at UE 1350 described in the DL. Each receiver 1318 receives aradio frequency signal through its respective antenna 1320, converts thereceived radio frequency signal into a baseband signal, and provides thebaseband signal to the multi-antenna receiving processor 1372 and thereceiving processor 1370. The receiving processor 1370 and themulti-antenna receiving processor 1372 collectively implement thefunctions of the L1 layer. The controller/processor 1375 implements theL2 layer function.
